Okay, so imagine you have a long piece of paper that is wiggly like a snake. This paper represents the yield curve. The yield curve is a big fancy word that just means how the interest rates change over time for different types of loans or investments.
Now, pretend you are going to walk along the paper from left to right. When you start on the left side of the paper, the interest rates for short-term loans (like a car loan or credit card) are lower because you don't have to wait very long to get your money back. But as you walk along the paper, the interest rates start to get higher for longer-term investments (like a 10-year bond) because you have to wait a long time to get your money back.
Now, imagine you are walking along the paper and you hit a bump in the paper. This bump in the paper represents something called an inverted yield curve. This happens when the interest rates for short-term loans are actually higher than for long-term loans. This might sound weird, but it can happen because people might think that things are going to be really bad in the future, so they want to save their money in long-term investments like bonds. This makes the demand for long-term loans higher, which then drives down the interest rates for those loans.
So, in summary, the yield curve is just a wiggly line that shows how interest rates change over time for different types of loans or investments. Sometimes the line gets bumpy and this is called an inverted yield curve, which means that people are maybe worried about the future and want to save their money for a longer time.
